INCU'BATOR.

No. 881,504. Speccaton i Application filed. August E,

Letters Patent. Patented nimh io, 190e.

1.907. Serial No. 387,715'.

To all Alolz/0m yit may concern:

it known that I, WiLLIAM E. TREDWAY, a citizen of the United States, residing at Nardin, in the county of Kay and Stateof Oklahoma, have invented a new and useful. lnoubator, of which the following isa speciiication. f

This invention relates to incubatore and more particularly to means 'for heating the interior thereof.

The obiect of the invention is to )rovide means whereby vvordinary chicken eathers can be used as a heating medium, the saine being so positioned. as to rest upon the eggs when the incubator is closed.

Another object is to provide a heater connected to the 'movable top of the incubator and normally maintained by gravity in an upright position when the incubator is either open or closed.

A. still further object is to provide an incubator having means whereby the same can bo conveniently opened.

lVith these and other objects in view the invention consists of certain novel features' of construction and combinations of parts which will be hereinafter more fully desiffrihed and pointed out in the claims.

ln the accompanying drawings, is shown the preferred form of the invention.

ln said drawings: Figure l is a perspective view ol" the incubator open. Fig. 2 is a section lthrough 'the pipe connection between the heater and closure. l

vReferring to thc iligures by characters of reference, 1i designates the body of the inl 'or 'thesaine having a tray 2 therein for reception of eggs and a drawer 2 loifated beneath the tray and designed to receive the chicks they are hatched.` The tray treated close to 'the top of the body l and the eggs therein aredesigned to bc contacted by a mass of feathers 3 secured in any suitable manner within the bottoni of a box 4 constituting the closure or the lid of the in,- cubator. rthis lid is connected to the body by means of hinges or in any other suitable manner and a spring 5 is preferably provided so that when thc lid is unlocked the same will auton'iatically swing into raised posi? ion :is shown in the drawing, this moveinf'nt being limited by a strap 6 such as shown and which may bc of any desired con-- struction and arrangement and is similar to corresponding straps used in connection partment is a pipe 8 extending through one` member of a water pipe 9 which is disposed close to the four walls of the compartment and designed to be filled with Water in any4 suitable manner. VPipe 8 extends beyond both sides of the cover'4 one of said rojectin ends constituting an outlet, w le the ot er end is closed and has an inlet openin 10. This portion of pipe 8 extends throng a heater l1 which may be of any desired form and is supported by the pipe 8 with the opening 10 in position to receive the' hot gases generated within the heater. he heater is designed to swing or oscillate on pi e 8 which thus constitutes a swiveled tu ular connection between the heater and the incubator lid. ,A suitable fastening device such as a hook l2 is employed for securing the lid a in closed position. l

In using the device herein described the eggs are placed in tray 2 and the lid lowered and fastened. The feathers are thus brought into contact with the eggs. The heat gen,- erated within the heater 11 is conveyed through the pipe 8 to the vpipe 9 where it heats the water. The air in compartment 7 is thus heated and comes into contact with the feathers and the eggs are maintained at the proper temperature. It is of course to be understood that a suitable tliormostatic controller such as indicated at 13. is to be used'in connection with the incubator. In the drawing cap 14 of the controller is shown swung backward from the lever but when the incubator is in use the same will of course assume a position directly above the heater.

- Vlf'hen it is desired to open the 'incubator the lid is nnfastened andthe sorin f 5 will )artl overcoi'ne the weight ol' the lid so that the upward movement thereof is greatly facilitated. As the. lid is swung upward thc "heater l1 turns u on pipe S and is maintained vertical. l t will be seen that thc device is very simple in construction and by providing feathers for the purpose of distributing heat over the eggs the device is rendered very ellicient.

What is claimed. is:

l. In an incubator the combination with an egg holding body; of a lid movably connectedto the body, feathers massed within the lid and disposed to contact with eggs in the body, andra heater `)ivotally connected with trunk lids and the like. A compartto and suspended from t alid.

2. In an incubator the combination with an egg holding body; of a spring actuated lid hingedly connected to the body, feathers massed Within the lid and disposed to contact with the eggs Within the body, a heater, and a swiveled tubular connection between the heater and lid.

3. In an incubator the combination With a body for holdin eggs; of a spring pressed lid hinged upon t e body,- means for secur ing the lid upon the body and against the tension of the spring, a soft material massed Within the lid and disposed when the lid is closed to contact with eggs Within the body, and a heater pivotally connected to and movable With the head. f

4. In an incubator the combination with a body for holding eggs; of a lid hingedly connected to the body, feathers massed within the lid, a water container within the lid, a heat conducting tube extending through the container and hd, a heater pivotally mounted upon and sup ing tube, said tu e being disposed to receive heated air from the heater.

In testimony that I claim the foregoing as my own, I have hereto aliXed my signature in the presence of two Witnesses. Y
